hello thanks for using 2CarPros.
fault code p0505 is related idle speed control system,it seems you have air leak of the intake system.
Here is a guide to check for air leak:

Start the engine and let it idle,check for air intake leak after mass air flow,if leak found repair it,if leak not found then perform throttle valve closed position learning and idle air position learning.check fig 1 for the procedure.
let us know what happens with you.
thank you.
